Levitating Superconductor Speakers - A Futuristic Way of Emitting Sounds

Apr 16, 2010
For his university project, James Coleman designed these futuristic levitating superconductor speakers that have a multitouch touchscreen wrapping them.

Inside their base, the speakers have a simple electromagnet.

The floating section of the speakers features a superconductor.

When turned on, the upper side of the speakers starts floating, and when you turn the music off the speakers become whole again.

The multitouch screen mounted in the base shows information on the music the user is listening to.

Speakers float thanks to the magnetic field of the built-in electromagnet which induces a field in the superconductor.

These speakers do not exist and cannot use superconductors (yet). Furthermore, they probably never will use superconductors when easier methods of levitation exist today.

Coleman designed his HYPOTHETICAL speakers for a class. The world record for highest critical temperature in a superconductor is -2.5 F. But most superconductors fail to operate if not cooled by liquid nitrogen.

A similar concept COULD be achieved using the "electromagnetic floater" concept. (Instructables has directions for building your own.) This uses a regular magnet whose height is carefully controlled by a feedback system involving sensors, electromagnets, and a computer chip.
